Reverse CW (on the Orion this is UCW) uses the upper sideband side of zero
beat. In reverse CW, as you tune up in frequency, the pitch of CW signals
goes down. In LCW mode, as you tune up in frequency, the pitch of the CW
signal also goes up.
True....and.... which one, USB or LSB, would most correctly be called
"reverse" is a matter for discussion.
Before I bought a Ten-Tec Omni VI, I had used a Kenwood TS-440, which
operates CW using upper sideband. I was used to that, and a bit annoyed
that the Omni VI could only operate CW LSB. I think that most rigs these
day give you a choice. My preference would be USB, though there is no
really good reason to have a strong preference for on over the other, I
suppose. With USB as the standard for many commercial and military SSB
operations, even below 9 MHz where hams switch from USB to LSB, I would
think that USB would tend to be the default. I have got used to the Omni
VI LSB CW operation. If it wasn't such a good CW rig, I would not have
got used to LSB CW.
